Nt-1

Nt-1 cannot be calculated. Usually it is given, since it represents the cumulative number of adopters so far (incl. period n-1). It is the base for your estimations of p,q and m. Once you have those p,q,m values, you can calculate Nt, Nt+1 and so on that will converge to m.

Calculating Nt-1

Hi, Nt-1 stands for the total number or the cumulative number of consumers who have already adopted the product. For example, you might have data for weeks 1-10 of the product launch. Then the total number of consumers who have purchased the product till week 10 = Nt-1. Hope this helps.

Marketing

Hey, I also want to know how to calculate the p and q number. Or are there any factors will affect p and/or q, which should be included in the marketing decision making process, i.e. advertising budget? Thanks
